Wedoany.com Report-Dec.7, EDF Power Solutions has opened a tender for Environmental Impact Assessment (EIA) services and related hazard studies for the HYODE (HYdrogen Offshore DunkerquE) project, an offshore green hydrogen production initiative located in France's Exclusive Economic Zone near Dunkirk.

The HYODE project will combine offshore wind generation with an offshore electrolyser platform to produce green hydrogen. It also includes onboard storage and ship-based transport to port, creating an integrated solution designed to advance large-scale offshore hydrogen production.

In the contract notice published on 18 November 2025, EDF Power Solutions explained: "The development of hydrogen production from renewable electricity is an important part of France's and Europe's decarbonization plan. Given the expected volumes of hydrogen, all decarbonized sources of electricity such as offshore wind must be utilized. In this regard, EDF power solutions aims, through a pilot project, to develop an innovative solution for hydrogen production by electrolysis at sea and the storage and transport of the hydrogen produced by ship to the port, thereby providing a significant boost to an emerging industrial sector."

The selected contractor will prepare all required documentation for the single-authorisation application in the EEZ, including the full environmental impact study, Natura 2000 assessments, protected-species derogation requests, and support throughout the public consultation and examination phases. The scope covers one to two offshore wind projects that will supply power to the hydrogen facility.

Applications must be submitted by 12 December 2025. The competitive tender process will run from 12 January to 8 April 2026, with the contract expected to commence in April 2026.

The HYODE initiative represents a pioneering step toward offshore hydrogen production in Europe, leveraging existing and planned wind resources to support the continent's growing demand for renewable hydrogen while testing a complete offshore-to-port value chain.
